All the selected strains do not produce violet colonies, instead produced pink or red coloured colonies. In a plate assay, among all the strains tested, Janthinobacterium sp. IARI-R-81 was most efficient in solubilization of K at lower temperatures of 5 and 10 °C and was closely followed by Janthinobacterium lividum (IARI-R-71). Janthinobacterium sp. IARI-R-70 did not produce any detectable halo zones at all temperatures except 10 and 25 °C.
